Maryland State Police’s Computer Crimes Unit served a search warrant at a home in the 5900 block of Applegarth Place in Capitol Heights on Thursday morning.

That’s where they found videos containing child pornography on Christopher Speights’ electronic devices.

“I’m sure other parents are going berserk, because they trusted him,” said a parent who asked not to be identified. She is the mother of one of Speights’ former students. "This is crazy, I'm in shock. You can't even put your kids in programs anymore, because you can't just trust the people that you're leaving your kids with."

A spokesperson for Prince George’s County Public Schools released a statement on Speights' arrest:

“Prince George’s County Public Schools (PGCPS) is aware that substitute teacher Christopher Speights has been arrested. We will cooperate fully with law enforcement in its investigation. Due to the nature of the claims, Christopher Speights will no longer serve the school district.

Any behavior that brings harm to a child will not be tolerated in any way in PGCPS. Over the past year, we have made significant changes to increase student safety and remain committed to ensuring a quality education in a safe environment for all students."

State police first received a tip about Speights in December 2016.

One parent tells ABC7 News that she is looking for answers from the school’s principal when students and faculty return from their spring break.

Speights is charged with three counts of distribution of child pornography and six counts of possession of child pornography.
